With the development of the Internet of Things (IoTs), widely distributed electronics in the environment require effective in situ energy harvesting technologies, which is made challenging by the unstable supply and severe conditions in some environments. In this work, a hybrid all‐in‐one power source (AoPS) is demonstrated for widely adaptive environmental energy harvesting. With a novel structure, the AoPS hybridizes high‐performance spherical triboelectric nanogenerators (TENGs) with solar cells, enabling the harvesting of most typical environmental energies from wind, rain drops, and sun light, for complementary supply. The spherical TENG units with a packaged structure can work robustly to collect energy from fluid. Nearly continuous direct current and a high average power of 5.63 mW can be obtained by four TENG units, which is further complemented by solar cells. Typical application scenarios are also demonstrated, achieving self‐powered soil moisture control, forest fire prevention and pipeline monitoring. The work realizes the concept of an environmental power source that can be deployed in the environment with high adaptability to make use of all kinds of surrounding energies for powering electronics in all‐weather conditions, providing a reliable foundation for the era of the IoTs.

基于高性能球形摩擦电纳米发电机的混合式多合一电源，用于收集环境能量

随着物联网（IoT）的发展，环境中分布广泛的电子设备需要有效的原位能量收集技术，这在某些环境中不稳定的供电和严峻的条件下变得具有挑战性。在这项工作中，展示了一种混合式多合一电源（AoPS），可广泛用于自适应环境能量收集。AoPS具有新颖的结构，可将高性能球形摩擦电纳米发电机（TENG）与太阳能电池混合在一起，从而能够从风，雨滴和太阳光中收集最典型的环境能量，以补充能源。具有封装结构的球形TENG单元可以坚固地工作以从流体中收集能量。四个TENG单元可获得接近连续的直流电和5.63 mW的高平均功率，太阳能电池进一步补充了这一点。还演示了典型的应用场景，实现了自供电的土壤湿度控制，森林防火和管道监控。这项工作实现了一种环境电源的概念，该电源可以高度适应性地部署在环境中，以利用各种周围的能量在全天候条件下为电子设备供电，从而为物联网时代的发展奠定了可靠的基础。
